Pro tip: get a Rx for your pens sent to a national pharmacy that your insurance supports, but don't fill it. That way, if you have this issue while traveling, you can just walk into a pharmacy and walk out in half an hour with what you need

Pro-pro tip for T1d's: If you relocate (or visit) the EU and get a Rx - IMMEDIATELY FILL it once as soon as you get it - otherwise it could be invalidated after 15 days - and it won't be valid when you try to use it the first time.

Or just bring a bunch of disposable needles with you and draw from your vials that you already have for filling your pump.
